ScienceMark 2.0 Primordia
Running ScienceMark's Primordia benchmark using Silicon gives you a nice CPU-limited benchmark that scales well with FPU and CPU frequency increases. With 2MiB of L2, the 660 is no faster than the 560. With the 3.46XE faster than any of the other P4s, the Primordia test enjoys a short main integer pipe over all the other CPU characteristics.
The Athlons' FPU power takes some beating though and even with only 1MiB of L2, they still rule the roost.
HEXUS Crypto
HEXUS Crypto is a small benchmark that does AES encryption on data, that I've been hacking on in recent times. Built in C# using the .NET framework, it should become generally available shortly. I designed it with raw FPU power in mind, just for this article. I aimed for a working set somewhere under 1MiB.
The P4s rank themselves by MHz with the Athlons doing the same, sitting higher than the Intel processors by virtue of FPU ability.
Realstorm 2004
Again, Realstorm is all about the FPU power, caring little for memory bandwidth (as long as it's enough) or cache size. The 3D renderer therefore ranks the processors by MHz and into two groups, one for the Pentium 4s and one for the unbeatable AMD64 processors.
